Comment 1 for bug 251759

I think I'm being affected by this same bug. If I put my top-level package directory next to my setup.py file, and I let buildout put the eggs in its standard place, bin/test will fail. See this thread:

Note that if I put the eggs elsewhere, or if I put my mailman directory under a src directory, then there's no problem.
